TYPE-WRITING MACHINE.

To all whom it may concern Be it known that I, BENJAMIN F. BARKER, a citizen of the United States, residing in El Paso, in the county of El Paso and State of Texas, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

This invention relates principally to means for centering headings on worksheets in typewriting machines.

According to the invention, there is employed in connection with a centering scale, (which may be on the carriage), an index, (which may be on the machine'frame), and this index is arranged to point to a special 0 when the typewriter carriage is. in position to begin a full line of-writing. In carrying out the invention,\the operator depresses the carriage-spacing key once for each letter in the word to be centered, and then notes where said index points on the centering scale. This will inform the operator as to the position at which to begin writing the word on the work-sheet; the operator then setting the carriage to said position by means of the. usual scale and index. Said 0 is the first point on a special scale which is preferably used in connection with said centering scale. Said special scale is of use in connection with centering. headings in cases where extra margin is provided for at the left-hand side of a work-sheet. The operator usually sets the margin gage for regulating this margin;

. and according to this part of, the invention,

the operator, after setting saidmargin gage, proceeds to adjust the new index to such point on said special scale as agrees with the position to which he has already set the margin gage. Then the operator taps the word on the space key, and the new index will thereupon indicate on the centering scale the number of the space at which thewriting of the word should be begun. Being thus informed of saidbeginning point, the operator adjusts the carriage to such point, and begins writing the word. In this Way, headings may be easily centered for different widths of margin or lengths of writing line. One of the scales which' is preferably employed has the usual scale for indicating the letter-space in the travel of the typewriter carriage at which the Specification of Letters Patent.

printing point stands, while another scale is adapted to be used to'properly center work in a line of a given length so that such work as a heading may be exactly centered therein. One of these scales is on the frame of them'achine, and has letter-spaces indicated thereon by means of a pointer carried on the carriage, while the other scale is on the carriage, and a pointer on the frame of the machine indicates the letter-spaces on said scale. Onelof said scales has an auxihary series of graduations on which one of said pointers may be set to correspond with the setting of a' margin stop, and said polnter may be arranged to indicate directly on the scale carrying said auxiliary series of graduations, the central letter-space of a line beginning at said marginal stop. With the help of said pointer and said scale, the point of beginning any work of said line so that it will be centered precisely on said line can be easily read ofi without mental calculations.

Other features and advantages will hereinafter appear. 1

In-the accompanying drawings, Figure 1 is a view showing so much of an Underwood typewriting machine with my invention applied thereto, as is necessary to the understanding of my invention. Fig. 2 is a detail section of the same. Fig. 3 shows the frame pointer indicating where to begin a word. Fig. 4 shows the carriage set to begin said word.

The carriage 1 of the usual Underwood typewriting machine carries a platen 2 rotatably mounted thereon, and around said platen is passed a work-sheet 3. Said carriage 1 is mounted to travel along the'frame 6 of the typewriter and carries a pointer 18 which indicates on' the usual indicating scale 7 the position at which the printing point of the carriage stands, said scale usually consisting of a series of gr'aduations marked or otherwise indicated, on a suitable strip or plate. Said carriage travels along such frame between right-hand margin stop 5 and left-hand margin stoipt 4. In using the present invention, the le -h-and margin stop 4 is preferably kept at the extreme left- ,hand of the machine, and the work-sheet 3 spaces are consecutively numbered, each one of'the said alternate letter-spaces preferably bearing its indicating numeral; and the altern'ate numerals may be offset, as shown in Fig. 1, for clearness.

. For a portion of the length of scale 11, be-

ginning as at the letter-space 40 thereon, is

an auxiliaryseries of graduations 12 having notation extending in the same direction, but in these graduations the successive letterspaces are consecutively numbered, preferably in red, to contrast with the numbering of the scale 11 which is in black. This auxiliary series of graduations coiiperates with I an adjustable indicator 9 which may he slidable along the indicating scale 7, so that the point 14': of said indicator may indicate letter-spaces .on said auxiliary graduations 12.

In the drawings (Fig. 1) the right-hand margin stop 5 is shown set at letter-space 20. To find the center of the line extending from 20 to 80 on scale 7, the

carriage is brought up against said margin stop, then the indicator 9 is set so as to read at 20 on the auxiliary graduations 12. This indicates the letter-space on scale 11,-

and therefore the letter-space 50 on the indicating scale 7 is the central letter-space of, the line. Similarly, if the right-hand margin stop is positioned at any other point along the indicating scale 7, and if the carriage is brought against it at such other point, then the indicator9, if placed at the corresponding point on the auxiliary graduations 12, will indicate on the scale 11 the central point of the line on scale 7 extending from said margin stop, 5 to the limit of the travel of the carriage. Said indicator 9 may also be used to properly center a heading on any such line. For instance, .after the indicator 9 has been positioned as above described, if a heading of four letter-spaces is to be inserted in the line beginning with the letter-space 20 and ending with the letter-space the carriage is brought as before against the margin stop which is at space 20 on indicating scale 7, the indicator 9 is then positioned at space 20 of the auxiliary graduations '12, and then the space-bar of the typewriter is operated four times. This moves the carria e so that the letter-space 20 on said auxi iary graduations moves away from. the indicator 9, and

' amaare a said indicator will, after said operation of the space-bar, indicate the letter space 48 the typewriter carriage is positioned with its pointer 18 at letter-space 48 on the inas many as the number'of times the spacebar of the ty ewriter was operated. The

scale 11 is pre erably so placed that the num- Y her 1 thereon is near the right-hand end of the typewrlter carriage, and the auxiliary -on the scale 11 as shown in Fig. 3. If now graduations 12 begin on said scale 11 at the letter-space number corresponding with the central letter-space of the indicating scale 7. Said scales 7 and 11 may extend to the right sufiiciently to show on said scale 11 any margin likely to be used in work on the typewriter.

It will be understood that the work-sheet 3 is to be so placed that the writing thereon will terminate short of the right-hand edge of said sheet with the margin stop 4 placed at the extreme left-hand position.

The indicator 9 may comprises bars 15 which extendtransversely of scale plate 11 on either side ofthe point of the indicator, the ends 13 of said bars being turned under said plate, as seen in Fig. 2, where they are joined together. The scale plate 7 is held slightly raised above the surface of the frame 6 by washers 8 ,which underlie its ends through which the screws holding said ends pass. I

The central portion of the scale plate 11 may be vertically ofl'set at 16 and 17 so as to stand clear of the usual lug 19 carrying the pointer 18, and, as the aforesaid portion is thus caused to face the operator vertically, the said pointer 18 extends through said scale plate, so that it forms in effect a fixed extension of said scale plate.

Variations may be resorted to withinthe scope of the invention, and portions of the improvements may be used without others.
